5 Claims.

. This invention relates" to" material dispensing: devices andparticularly'to? devices: for: dispensing: rolled or reeled stripmaterial;

My invention has numerous: applications but I:

5' have chosen toiHustrate"andrdescriberit herein as. applied to anapparatus-fora dispensing a strip' of paper from a. supply: roll. 1

In various" classes: of: apparatus;v illustrative of which iselectrically. operated.quotation tickers; telegraph typewriters etc., itis-desirable to: feed through the said apparatus a; relatively narrowstrip: of paper and to supply the. samerfrom: a roll or reel.

It is desirable also" to enclose the supp 'yroll of paper in asuitable'ienclosing: means= such;1or example. as a cabinet. other.housing: to preserve the same against mutilation, tov keep it. cleanetc;

When the. supply: roll of. paper concealed from view, itbecomesdesirabl'eto know the quantity of the supply on the roll? as itis'=c0ntinuously used, so that as. the. supply roll: approachesthe endof the strip a new roll maybe: charged-into" the cabinet 'to avoid".interruption of the strip feed in the said apparatus;-

It is therefore one of the objects of my: invention to provide a.rol1ed1material dispensing device whereby the quantity of' the. material'on aconcealed roll may be at all timesindicat'eda Another object of myinvention"is to provideanimproved containing cabinet. for a row' ofdispensable material such asapaper: strip or the like, and provided withan" externally" visiblemeans for indicating the quantity of a the supplyroll in the ca'binet.

Another. object is to provide a dispensing c'abi netfor rolled: materialprovided with: externally visible indicating means adapted" to indicatethe decreasing diameter of the" roll of material a's it isdispensedi'from the cabinet;

Another object is to provide a rolled material dispensing cabinet havingexternally visible in dicating means for indicating the quantity of 1rolled materialavailable in the c'abinetf'or-dispensing andwhich willbe'simple' construction andin' which the indicating mea-n'smayjfunctionwithout interfering withthe replacing of'an ex hausted or substantiallyexhaustedroll and th'e installation of a succeeding supplyrolll Otherobjects willbe apparent to those skilled in the art to whichmy'invention appertains.

My invention is fully disclosed inthe'follo'wing description taken inconnection with the accompanying drawing, in which:

Fig. l is-a view illustratingar.mechanismembodying my invention and.showing in cross-section a part of an enclosing cabinet therefor;

Fig; 2'isa view taken from the plane 2 of Fig. 1; and

materialon Fig; 3 is-a view-taken from the plane 3 of Fig. 1. Referringto the drawing, I have shown at 1 and: 2 side walls of an enclosingcabinet, the

walls being.representedfragmentarily to simplify the drawing, but whichas those skilled. in this will be understood by art may be of anydesired extent'to completely enclose the roll of dispensable, material,3,,to'be referred to later. The cabinet may also comprise a rear wall 4and a wallopposite the wall 4 which is not shown in the; drawing.inasmuch, as" the cabinet isnillustrated in cross+section as abovementioned. The-walls 1',

2a-nd4. may beprovided with a: closing door 5 hinged-to the panelzl asat 6 and adapted to-be,

latched tothe panel 2 as, for example, by the device indicated generallyat 7 comprising an eye 8 onlthe wall'2 and'a hook 9 pivoted on the door5.

Upon the door 5 andinternally off the cabinet thus providedissecureda'bracket 10 comprising as foot 11 secured to the door 5 as by screws 12and comprising an upstanding post 13 to the upper: end? of whichv ispivotally mounted a bell crank device 14, the pivot connection thereofcomprising a screw 1'5 having a reduced portion lfil'and" a threadedportion 17 threaded .into the post 13. l Therbell crank device lepivotsupon the reducedrportion 16 of the screw and'c'omprises a forwardlyupwardly extending arm 18 and a downwardly extending arm .19 at anangleto the arm. 18.- r

At". theoutenfree-end of the arm 18, it is pro- VidBdfWithiliStUb shaft20 upon which is rotatably mounted'aroll-s 2l of: dispensable materialsuch as a stripof paper, the-strip being indicated at 22andwadaptedto'be dispensedfrom the roll 21 by the rotation of thelatterxupon the shaft 20, the

stripextendin'g fromthe roll 21 through a suitable slot or otherperforation 23 in the door 5.

The-peripheryof the rol1'21 rests upon a roller support-1 25,;being:maintained thereagainst preferablybyathei action of: gravityon the roll21 and the roller 25 is' rotata'bly. supported on v the shankofazscrew26fthreaded into a post 27 which has a horizontal" foot 28isecured to the inner face of. the: door 5. asbya1,s'crewv 29.

A disc or'sother' plate 30 issecured' to the door 5=inwardiy thereof.as. by screws 3l3'1 andhas pivotallymountedthereon a .dial finger 32,the pivotconne'ction being provided :by a screw 33 screwed: into theplate 30 and: extending through a suitable perforation in one end of thedial finger 32. The dial finger 32 is disposed generally parallel: and?spaced: inwardly from" the door 5 and at? its endopposite' thepivot33isbent to the) right at. substantially" as right angle-and extends:through: an: arcuate slot? in the door 5 andzonrthe=extreme rend aportion where: it emerges a direction parallel with the outer surface ofprovided with 'material is in the cabinet.

the door 5 as at 36 to provide an indicating point. An intermediateportion of the dial finger 32 is an upstanding post 3'7 having adjacentits free end. a neck 38 formed therein. A connecting link in the form ofa wire 40 has one end bent to encircle the neck 38 and at its oppositeend is bent to form a hookwhich is hooked into a perforation 41 in theend of the arm 19. f

Upon the outer surface oi the door 5 and substantially coextensive withthe arcuate slot 35 is an indicating scale comprising suitablesubdivision marks 42 and having the characters E and F at the extremeends of the scale which signiiy the words empty and full respectively.The scale marks 42 and the slot 35 are arcuate around the center of thepivot 33.

The length of the link 40 and the relative positions of the arms 18 and19 are so provided that when the roll 21 is full of strips to bedispensed, and when the roll rests upon the roller 25, the indicatingpoint 36 of the dial finger 32 will indicate the scale divisioncorresponding to the letter F and thus indicate that the full roll ofihe stiip 22 may now be dispensed out through the slot 23 and as theroll 21 diminshes in diameter, the arm 18 is moved correspondinglyclockwise as viewed in Fig. 1, the action of gravity maintaining thedecreasing periphery of the roll 21 always in contact with the roller25. This exerts a pull upwardly as viewed in Fig. 1 of the link 40through the agency of the arm 19 and moves the dial finger 32 clockwiseas viewed .in Fig. 2, causing the indicating point 36 to move upwardlyover the scale, Fig. 3, toward and ultimately reaching a positionadjacent. the character E.

Thus the indicating point 36 indicates at all times the quantity ofdispensable material still on the roll 21.

- When the roll is exhausted or when it is desired to renew the same,the door 5 may be opened by unhooking the latch 7 and the arm :18 may beturned counter-clockwise as viewed in Fig. 1 to free the roll from theroller 25, and the dispensed roll may be removed and a new one placedupon the stub shaft 20; and as will be readily understood, this simpleoperation is not in the least degree interfered with by the presence ofthe indicating mechanism comprising the link 40, finger 32 etc.

When it is desired that the roll 21 shall move by gravity and againstthe roller 25 and be maintained 'thereagainst, the cabinet may restnormally upon the wall 2. However, the cabinet may be disposed to restupon the wall 4, in whichcase, a spring'50 may be provided secured atone end to the cabinet wall 1 and at the other.

end to the arm 19 to resiliently constrain'the bell crank device 1-.-toward clockwise movement to maintain the roll 21 against the roller 25.

My invention is not limited to the exact details of construction shownand described. Many changes may be made therein without departing fromthe spirit of my invention or sacrificing its advantages.

I claim:

1. In a roll material dispensing device, a cabinet, a hingingly movableclosure member for the cabinet, a movable supporting member adapted torotatably support a roll of material to be dispensed, a stationaryabutment engageable by the periphery of the roll of material, a movable'by the roll material indicating means so connected with the supportingmember as tobe moved by movement of the supporting member upondiminution of the roll diameter occasioned by dispensing material fromthe roll, the supporting member and the abutment being mounted on saidclosure member whereby they are adapted to be moved outwardly from thecabinet with the closure member wheremay be easily replaced. 2.
